Johanna Konta swept aside seventh seed Sloane Stephens today with an extraordinary display to reach her third grand slam semi-final at the French Open.

It was scarcely believable that this was the same player who had never won a main-draw match at Roland Garros before this year as she raced to a 6-1 6-4 victory in a flurry of winners.

Stephens lost in the final last year to Simona Halep and had been backed to get there again but she was powerless to stop Eastbourne's Konta, who hit 25 winners in the match and only dropped one point on serve in the second set.

By reaching the last four, Konta has matched her own best grand slam performances at the Australian Open in 2016 and Wimbledon the following year, as well as the performance of Jo Durie, who was the last British woman to reach the last four here in 1983.

Konta said in her on-court interview: "This is my first match on the new Chatrier and to play one of the best players in the world and to play at the level I did, I feel very proud of myself. I'm just so pleased to have gone through.

"Definitely dealing with the conditions out here, it's super windy, and an opponent like Sloane who can run away with that match. I'm just pleased I was able to keep her on the back foot."
